In a void in the solar system, the 'Kuafu' spacecraft flew rapidly in the void, with a speed of more than 200 kilometers per second, which has surpassed the fastest historical record in human history, and its speed is still soaring.

But the void is too vast, even if it is a speed of hundreds of kilometers per second, in the boundless void, the Kwafu spacecraft still seems to be still stationary at the origin, as if there is no change at one point forever, not to mention the universe, the solar system is too big.

In the Kwafu spacecraft, everyone is lying on their space chairs, playing games in the virtual world with their virtual watches, chatting with friends and relatives, and feeling the powerful push back when the spacecraft accelerates.

The engine of the Kwafu spacecraft has a powerful thrust of 800 million tons, and the mass of the spacecraft itself is only one million tons, even if it is all the things in the spacecraft, its mass is only more than 2 million tons.

This mass, compared to the 800 million tons of thrust of the engine, is simply insignificant.

"Acceleration ~ Acceleration ~"

The speed of the ship is still soaring, but in order to take into account the pressure resistance of the crew on the ship, the acceleration process of the ship is not too fast, it is a continuous acceleration process.

This time the scientific expedition around the solar system needs to sail too far, and there is not enough speed, and this spacecraft does not know that the year of the monkey can complete the mission of the scientific expedition.

The earth gradually becomes smaller in the field of vision, and finally slowly disappears, and there is no trace of the earth at all with the naked eye, according to the calculations and plans of scientists.

The first stop of the Kwafu spacecraft was Mars, where it was headed.

Mars and Earth have too many similarities, both have atmospheres, the speed of revolution is about the same, the speed of autobiography is only 41 minutes, and the surface temperature difference of Mars is not too big, of course, this is compared to other planets in the solar system.

In addition, Mars, like the Earth, is in the habitable zone that scientists consider to be habitable in the solar system, and the so-called habitable zone is an area that scientists believe is only possible to give birth to life and be habitable within a certain range.

For example, in the solar system, the habitable zone refers to the range of the four planets Mars, Earth, Venus, and Mercury.

Once this range is exceeded, because it is too far away from the sun, the light is not good, and the temperature is very low, it is impossible for life to be conceived and reproduced.

Therefore, with the asteroid belt as the boundary, the inner circle can also be called the inner circle of the solar system, and the outer circle of the solar system can be called the outer circle of the solar system.

Because Mars has too many similarities with the Earth, it has always been considered by scientists to be the most likely planet for interstellar immigration, and there are many science fiction movies and science fiction about Martian immigration, Mars transformation, etc.

And scientists also deduced through the analysis of everything that exists, that Mars may have given birth to very prosperous life like the Earth in history, but then I don't know what the reason is, Mars slowly withered and eventually became a dead planet.

Scientists want to go to Mars to investigate, to find life on Mars, to explore the traces of life on Mars, and to investigate whether Mars can become a planet for human settlements.

Of course, if Mars once really had life, then we can also find out the reasons for the demise of Martian life through the investigation of Mars, and check the extent to which Martian life evolved when Martian life was prosperous, whether advanced life was born, and what the outcome of these advanced life is.

There are many, many things waiting for scientists to explore, to discover.

So when the figure of Mars appeared in the field of vision of the Kuafu spacecraft, the scientists on the entire spacecraft became excited one by one.

As the spacecraft gets closer to Mars, its speed is slowly decreasing, and the gravitational pull of Mars is only about 40% of that of Earth, which means that if the spacecraft wants to be captured by Mars' gravity, it will have to be slow enough.

"It's hard to imagine how prosperous Mars would have been if it had had life."

Long Zhankong passed through the telescope on the spaceship and began to observe Mars from a distance.

Unlike Earth, which is a blue gem, Mars is a reddish-yellow planet, and its atmosphere is very thin and only about 1% of the Earth's atmosphere, so the surface of Mars can be clearly seen in the sky.

It's very barren, it's a world dominated by red.

"Even if there was life, I don't know how many billion years ago, the entire solar system has a history of 4.6 billion years, and in such a long period of time, the history that we humans know now is simply insignificant."

Next to Long Zhankong, Huang Zhibin is also constantly observing the red planet in the void, as a cosmic astronomical scientist, he also has a strong interest in the history, evolution and development of the solar system.

In another part of the spacecraft, the simulated ecological area, Liu Daoming and Li Jingxuan, who also graduated from the first class of Biological Sciences at Galaxy University of Science and Technology, are studying the growth of plants in a weightless environment while discussing life on Mars.

"In the weightless environment, the genetic mutation of plants is very frequent, and the impact on animals is greater, in space, these mice almost all lose the ability to reproduce the next generation, it is estimated that the weightless environment, the secretion system in the animal, the genetic system and so on have an impact."

Liu Daoming carefully observed the plants and animals in the simulated ecological area, and after his long-term observation and research in space, he also found that the weightless environment has a great impact on plants and animals, and animals will be very uneasy in space, difficult to adapt, and many times will not eat or drink.

"Don't talk about that, do you think there will be life on Mars?"

"There is water at the north and south poles of Mars, and when there is water, it is very likely that life can be born, especially the environment of Mars is relatively mild, and I estimate that there must be life under the glaciers of the north and south poles of Mars."

Li Jingxuan looked out the window, a red planet stood quietly in the void, and scientists who study biology will be obsessed with finding the origin of life.

Just as cosmic astronomers want to figure out the origin and evolution of the universe, and how big this encounter is, biological scientists are also looking for the origin of life and how far life will evolve in the future.

"There have always been two views on the origin of life: one is the idealistic view, which holds that life and all things were created by the so-called God; Another materialist view has emerged with the continuous development of modern science and technology, which holds that life on Earth is created by accident by extraterrestrial meteorites or chemical reactions on the earth itself. ”

"Let's not talk about the idealistic viewpoint, the micro viewpoint is deduced according to the existing biological science and technology, especially Darwin's theory of evolution, coupled with the emergence of genetic technology, almost all organisms can trace the original and simplest life if they go to the source and explore."

"So now scientists basically believe that life is a chemical, physical and other comprehensive reactions, different molecules interact with each other, mix to produce the original organic molecule with DNA, DNA has two qualities: first, it can make amino acids, second, it can replicate itself, DNA these two characteristics are also the basic characteristics of organic organisms like bacteria, and bacteria are the simplest life in life, and it is also the oldest fossil we can find."

When it comes to the origin of life, Liu Daoming suddenly came to the spirit, as a biological scientist, he has also been thinking hard about the very serious issue of the origin of life.

However, the history of the earth has been billions of years, and the history of life is also very long, and what happened in the long years calculated in hundreds of millions of years can only be studied and inferred through some fossils in modern times, but it is very difficult to trace the source.

Although life is also composed of various molecules, and all kinds of things in the body of life are dead when taken out alone, when they are put together, they are life, which is very magical!

You can imagine that these substances in the human body are very common in nature, but after the combination, man, this amazing life is born.

"The birth of life is not necessarily related to water, but our current cognition believes that without water, there can be no life, but there are many ideas in science fiction movies and science fiction, carbon-based life, silicon-based life, energy body life, mechanical life, and so on."

"The universe is too big, we know too little, too little now, and we are now sitting in a well and watching the sky."

"A planet with water does not necessarily have life, and a planet without water does not necessarily have no life, I think life may exist widely in the universe, maybe life can be found on Mars."

Liu Daoming put down the work in his hand, came to the window of the spaceship, and looked at the planet in the void, although it was not as moving as the earth, exuding an intoxicating halo of life.

But at this time, Liu Daoming can't wait to fly to Mars immediately, to explore the traces of life on it, human beings are too lonely, so far no extraterrestrial life has been found, so that sometimes human beings sit in the well and watch the sky and say that human beings are the only life in the universe.

PS: Are there any aliens? Everyone can talk about it, and it must be justified and well-founded~
